Entering a Measurement
To enter a specific Failsafe Material Level within -50 to 150% of Span (P007), in Units

Relay reaction
The way in which relay programming reacts to the failsafe level depends on P129 Relay
Failsafe (page 132). By default:
• Alarm relays have P129 = OFF and so react to the Failsafe Material Level.
• Control relays have P129 = dE and so de-energize the relay when the unit enters
Failsafe mode regardless of the Failsafe Material Level.
P072 Failsafe Level Advance
Sets the speed the HydroRanger 200 advances to and returns from the Failsafe Material
Level.
